Yeah, probably worded that wrong and made it sound like they are one and the same. As I wrote previously, they are certainly not two traits you would want to have in unison.
Depression is a serious issue and I agree with you fully here again. To appease Cult3's anger, I will state here clearly that having depression does not make you weak minded or a lesser person. Perhaps in the examples you listed here the decisions are made as much for the sake of the person themself, than for the organisation. That being said, Boyd has also shown IMO that he does not strive against the odds in the same way that a Lockyer, Langer, Thurston, Johns, Webcke etc. have and these players are the ones who are noted in the history books of the NRL as being match-winners and game changers.
McHunt?
